Information
- B&R X20AI2632 combines two-channel acquisition with programmable scaling and signal recording, allowing a paired measurement to be evaluated in the controller.
Voltage input: +/-10 V
Current input: 0 to 20 mA
Both inputs are converted in 50 microseconds. The nominal voltage increment is 305.176 microvolts and the nominal current increment is 610.352 nanoamps; these conversion increments are not accuracy specifications.
A 500 Veff channel-to-bus isolation test rating does not imply isolation between the two channels. Keep signal common-mode voltage within +/-12 V and retain the configured filter, scale and sampling cycle during replacement.

Application scope: The technical values apply to this model in the specified installation and configuration. The examples below address the stated product function.
Paired measurement signals
Acquire two related analog measurements without reserving a four-channel module.Current-loop acquisition
Read 0 to 20 mA transmitters after checking loop burden and signal reference.Low-loading voltage inputs
Measure +/-10 V signals through the 20 megohm voltage inputs.Recorded signal comparison
Use configurable recording and scaling to compare the behavior of the two inputs.
Record whether X20TB06 or X20TB12 is fitted before moving field wiring.
Identify whether each transmitter uses the voltage or current positive terminal and retain the negative return.
Verify the transmitter can drive the complete loop with less than 400 ohms added by the module input.
Measure the reference relationship between the two signal sources before connecting them.
Check the application signal type after restoring wiring.
Restore each input filter with its engineering-unit scale and sampling cycle.

Technical notes
Trace each positive signal lead: Identify whether each transmitter uses the voltage or current positive terminal and retain the negative return. Mark both channel numbers so the two process values are not exchanged during a terminal-block transfer.
Restore the selected input range: Check the application signal type after restoring wiring. Voltage values use signed INT data, while the current range starts at zero. A positive voltage alone will not expose an incorrect sign interpretation.
Retain the acquisition settings: Save the two filters, scales and sampling settings with the accepted test results. When using recording functions, keep their trigger conditions alongside the captured values so a later trace can be compared meaningfully.
FAQ View All FAQ
-
Which terminal block is intended for X20AI2632?It is designed for X20TB06. X20TB12 can also be used, but the channel connections must still follow the six-signal input arrangement.
-
Does X20AI2632 require a different module for current and voltage?No. Each input accepts either voltage or current through different terminals; the wiring and configured signal interpretation must agree.
-
What does one voltage count represent on X20AI2632?One least-significant count represents 305.176 microvolts in the +/-10 V range. This is resolution, not a guarantee of total measurement accuracy.
-
How much burden can X20AI2632 add to a current loop?The current-input load is less than 400 ohms. Include that burden when checking the transmitter supply and remaining loop voltage.
-
How quickly can X20AI2632 update the pair of converted inputs?The conversion time is 50 microseconds for both inputs. The effective application update also depends on the configured sampling and bus cycle.
-
Which raw value represents current-range overshoot on X20AI2632?The converter output reaches 0x7FFF at current-range overshoot; current undershoot produces 0x0000. Interpret these states with the channel diagnostics.
-
Can X20AI2632 filters be assigned separately to the two inputs?Yes. An input filter can be configured for each analog input, allowing each signal to retain the bandwidth needed by its measurement task.
-
What should be checked before using two differently grounded sensors with X20AI2632?The inputs are not isolated from each other. Check their common-mode potentials against the +/-12 V range and confirm the shared reference arrangement.
